outer bandsbeing of bronze and formed g with the worm teeth. Thetwo bands are held together by avplurality of pins 36.l

The coupling between the inner and outer rings is of .theoverrunning clutch type, and 'is .preferablyA positive consisting of pawls 37 on the inner ring normally urged out'- Wardly by springs 38 to engage ratchet teeth 39 on the inner band. s

On one sideof the worm wheel 31 is a sliding gear 40 for iirst speed. A reverse ribs.

mechanism of conventional'type is associated with vthe sliding gear but for the sake of clarity is not shown' inithe drawings.

On the'` othery side ofthe wormwheel 31 a pair of'sleeves 41 and 42 are splined on the countershaft. The 'inside sleeve 41 adjacent-the worm wheel is formed with 'a central annular `rib43having teeth 44. .The

` outside'sleever 421has asimilar rib 45 at its inner end provided. with teeth-46. Gear Wheels 47 48,:and `49 vare mounted on bearings on the sleeves and are separated vby the gear 48 for secondr speed and the gear 49 for fourth speed. The gear. 49 has teeth 5001i its hub and a clutch collar 51 engaged therewith is yslidable into and'olut of engagement with the teeth 46of the rib 45. 'A Ay clutchcollar 52 on the rib 43is engage-A able with teeth 53 on the hub ofthe gear 48. The'clutch collar 52 is also provided with,

oney or more laterally Zprojecting teeth '54,'

movable into and out ofapertures 55 in the gear 47. As yindicated in dotted lines jin Fig. 2 the teeth 54 may engage only. the gear 47 f or they may Abe moved further to theleft to engage between the pins 36'x'and thereby couple the gear 47 directly tothe outer ring of the worm wheell 31.'. This lastjposition of adjustment will'cut out the voverrunning element ofthe vworin wheel and enable the braking action of the motor yto be employed when desired. y I The gear wheels 40,47, 48, and 49 mesh with mating gear wheels 40a, 47a, 48a, and l49a on the lower or second'countershaft 30, all except the gear 40 being in constant mesh. The drive is taken through thegear wheel 47a to a gear wheel 56 fast on one side' of The gear 47 is for"v third speed,"the

Vrear walls ofthe cylinders;

ential are fast on the divided drive shafts 59-59 The housing 57 is coupled at each side to a sleeve 60 embracing the drive shaft. The sleeve carries one' element 61 of the steering V clutch,Fw'vhile the other'element' 62 "the clutch is likewise lon a sleeve extending outside the body 5 and terminallycarrying a track-driving sprocket wheel 63. The

shaft 59 extends beyond thes'pr'ocket wheel andcarries a smaller sprocket Wheel 64.`

Therear end of the transmission shaft carries a. gear 65 meshing with a gear 66.
